Notes: After about four months off without processing any images (I was taking them, just not processing them) I'm back with an image of M82(on top) and M81 (below).

This was taken at my home observatory and is an LRsGB with a synthetic green channel and Ha blended into the red channel. The Ha (hydrogen alpha filter) helped to bring out some of the active star forming regions (the red areas) particularly in M82 which is being severely distorted due to the huge gravitational pull of it's companion galaxy.

These two galaxies will eventually merge which is what will also happen to our own Milky Way and the Andromeda Galaxy.

BEAUTIFUL! It's a breathtaking image. It remind me of the String of Pearls comet. I like all the minute details.

did you actually take these pics. and where is our galxy i mean like it does not end

Yes, I actually took these pictures from my back yard observatory.

And you're right, it's a big universe out there. Everytime we build a more powerful telescope we see further and further out so at this point in time no one knows when and if we'll ever find the end of the universe.
